What is the medical term meaning hinge joint?

The medical term for a hinge joint is ginglymus. A hinge joint is a joint that allows movement in one plane, like a door hinge. It is formed by the articulation of two bones, with one bone forming a convex surface and the other bone forming a concave surface. The convex surface fits into the concave surface, allowing for movement in one direction only. Examples of hinge joints include the knee, elbow, and ankle joints.
